about Canon G9 raw and dcraw..again

Unread postby PJ2 » 24.09.2008 22:11

My contribution to ongoing conversations:
Yesterday night, Helicon v4.84 was running smoothly on my vista sp3 system.
I was finding it worked better than the software supplied with my canon G9.
It did produce nice conversions with dcraw higlight recovery at -2 or -3.
It started loading cR2 by identifying the files as 16bit (I was interested to see that) and 4000x3000, which was correct.
Today, I made the mistake of upgrading to v4.88. A disaster.
It reads theG9 raws as only 8bit and low definition, 1600x1200.
And the image is a pale, flat mess.
There is also the '1400' bug message when iHF refuses to exit.
I downloaded the 4.87 version, as suggested on this forum, but 4.88 refuses to be uninstalled by it.
I would appreciate constructive suggestions, at least an opportunity to download 4.84 again, as it was working so well.
Thank you

We will publish 4.90 today, please check if this help.
Please note that 16-bit option for DCRAW disables white point correction so images may look flat.

about hf 4.90 and canon G9 raw

I registered for this forum but declared myself as PJ2 yesterday.
I installed 4.90 as soon as I could and was not disappointed.
All the flaws of 4.88 seem corrected, and the default values for dcraw are perfect.
Now I shall explore what advances have been made since my well-practised 4.84.
I may then write a little report on the superiority of HF over the software supplied with the canon G9 to process raw.
Keep up the excellent job you are doing.
